As long as you don’t expect any real world performance gains without tuning you’ll get what you’re after. The easy place for 50/50 meth/water for cooling is in the charge pipes just before the I/C. Results are mediocre but measurable. The best place is in the manifold just after the I/C. Results are good but there’s a lot of work to get to that location and you better get your jets right the first time because you may not have access after the install. A few are mounting in the intake pipes ahead of the turbos. There appears to be good results from this location but you have to run at least 90% meth which requires upgrades to all of the lines/parts over the standard meth/water kits.

I have mine mounted pre I/C. I show a measured IAT improvement in the 1/4mile but zero net gains in performance. The smallest jets in the AEM kit work best for me but there’s solid evidence that the medium jets work better when tuned. If you choose a post I/C location, just make sure you’re not spraying in a direct path of the MAP or IAT sensors.
